It came from a mama dino. (nah, I really dont know where the dino came from -shrugs-) I'm not a chicken so...
Chicken. No doubt. For an egg to be incubated, if would need a chicken to sit on it. The temperature coming from any other animal would not be suitable - only the chicken itself could recreate the perfect degree of warmth for incubation. So if the egg was created first, with no chicken, it would be almost impossible that it became incubated in order to hatch. A chicken that was already hatched would be required, an hence the paradox would eventually prove untrue, with the chicken, and not the egg coming first. But then here's a real paradox. One day Pinocchio said "My nose is long!". Obviously he was lying, because his nose was had not grown longer as it would whenever he told a lie. However, as stated above, he lied, and therefore his nose WOULD grow longer. But then his statement would then be TRUE, because his nose was long. And hence his nose would grow longer while it was not growing longer. TOTAL PARADOX. Problem?
Josh, think about it. You think a chicken would fit into a category with the dinos? Your paradox is flawed, my dear sir, from the very beginning. An egg could be incubated by other reptiles, and the chicken was a hybrid (most likely). So therefore, the egg came first. Dino = laid egg = hatched = chicken. HA.
You guys are really stupid!! The chicken nor the egg came first. God created the chicken or at least the very first chicken ancestor. Then the chicken ancestor gave birth to eggs and the eggs hatched to baby ancestor eggs and so on!! Understand guys!!!!
Chamis, honestly? Be more realistic. God zapping a chicken? Dinosaurs were before the age of humans. Chickens belong to our era. Not when the ice age didn't happen yet. So honestly, we're not the stupid ones. :3 Logic, my dear Watson. Logic.
No shit, Sherlock. And give Pinocchio some respect - all he wanted was to be a real boy. Has there been any evidence to prove that reptiles other than the chicken are able to incubate a chicken egg?
